I didn’t put much stock in the possibility that a Dominican spiritualist working out of a basement in Union City, New Jersey, would have much to say about a lampshade that might have been made from human skin in a Nazi concentration camp. But there I was, sitting across from Doña Argentina, a large woman wearing a ceremonial headdress and smoking a pair of cigars, one on either side of her mouth.

Nazi eugenicist propaganda themes resonate wildly with all sorts of tribalism and racisim, and so they still kill, in modern ghettos and parlors. There are a few scientists who were effective at putting some of those evil ideas to bed; one of them, George Williams, recently died let's hope his ideas remain pervasive much longer than he lived.
